Wage Benchmarking for Industrial Maintenance Contractors

The Call You Did Not Want on a Thursday Afternoon

Your maintenance supervisor forwarded you a resignation letter at 3:47 p.m. Your best pipefitter is leaving for a refinery twenty miles down the road. He says they offered him $6 more per hour. You have no idea whether that number is real, inflated, or right at market — because nobody at your shop has ever sat down and built a formal pay structure for the trades you hire.

That is the moment industrial maintenance wage benchmarking stops being a nice-to-have and becomes an operational fire.

Industrial maintenance contractors sit in a position that is both familiar and frustrating when it comes to compensation data. You hire the same SOC codes as construction specialty contractors — welders, pipefitters, equipment operators, sheet metal workers — but your firm lives under NAICS 2389 (Other Specialty Trade Contractors) or adjacent industrial-services classifications, which means generic "construction wage" resources often feel like they were written for someone else's business. The underlying BLS occupational data, however, does not discriminate by your NAICS code. The same SOC taxonomy that benchmarks a union electrical contractor in Houston benchmarks your maintenance techs in the same city. You just need to know how to read it.

This guide shows you exactly how to do that.

Why Industrial Maintenance Contractors Share the Construction Wage Problem

NAICS 238 — Specialty Trade Contractors — covers establishments that perform specific trade activities, typically subcontracted from general or industrial contractors (BLS). NAICS 2389, Other Specialty Trade Contractors, is the catch-all sub-sector that captures everything from industrial insulation crews to structural maintenance shops that do not fit a single cleaner trade category. If your firm does turnaround and shutdown work at chemical plants, maintains heavy equipment at a mining operation, or handles mechanical integrity work at a refinery, you almost certainly live somewhere in this classification range.

Here is what that means for pay: the people you are hiring — welders, pipefitters, construction equipment operators — carry the same SOC codes as the construction contractor across town. BLS OEWS (Occupational Employment and Wage Statistics) organizes wage data by SOC code and geography, not by employer NAICS. Your competition for a certified pipe welder is every industrial employer in your labor market, including refineries, petrochemical plants, shipyards, and the specialty trade contractors doing the same turnaround work. Knowing the BLS national median for a SOC code is the floor of your benchmarking process — a reference point that tells you where the market starts, so you can understand how your geography, your shift schedule, and your benefits package stack against it.

The national figures, published each May by BLS, are the authoritative baseline. Your local rate — your actual competitive number — lives at the state or metropolitan statistical area (MSA) level and may be higher or lower depending on your industrial cluster. We will flag where to find those geographic figures shortly.

The Four Core Trades in Industrial Maintenance Wage Benchmarking

Most industrial maintenance shops draw from a consistent set of SOC codes. Here is what the BLS OEWS May 2024 data shows at the national level for the trades you are most likely pricing offers against right now.

Welders, Cutters, Solderers & Brazers (SOC 51-4121) National median: $51,000/yr. The 10th percentile — the entry point for the workforce — sits at $38,130/yr, and the 90th percentile, where your most experienced certified welders land, reaches $75,850/yr (BLS, May 2024). The spread between the 10th and 90th percentile is nearly $38,000 — which means "welder" is not a single rate. A certified pipe welder with structural experience commands a materially different number than a production floor tack welder, and your offer needs to reflect that distinction. See our full welder salary guide for a trade-by-specialty breakdown.

Plumbers, Pipefitters & Steamfitters (SOC 47-2152) National median: $62,970/yr ($30.27/hr) (BLS, May 2024). BLS publishes plumbers and pipefitters under a single wage series — SOC 47-2152 — so you will not find a separate national median for pipefitters alone in the OEWS tables. What you will find is a single authoritative number for the combined occupation group: $62,970/yr. For industrial maintenance shops doing process piping, steam systems, and mechanical integrity work, this is the benchmark anchor for your pipefitter offers. More detail on how to apply this figure to industrial service contracts is in our pipefitter salary guide.

Construction Equipment Operators (SOC 47-2073) National median: $58,320/yr. The 10th percentile is $39,850/yr; the 90th percentile is $99,930/yr (BLS, May 2024). If your maintenance crews run cranes, excavators, or heavy lift equipment on industrial sites, this is your benchmark SOC. The 90th-percentile ceiling above $99,000 reflects just how wide this market is between an operator running a compact loader and a licensed crane operator on a refinery turnaround. See our heavy equipment operator salary guide for how to anchor offers by equipment class and certification level.

Sheet Metal Workers (SOC 47-2211) National median: $60,850/yr ($29.26/hr) (BLS, May 2024). For maintenance contractors doing ductwork, insulation jacketing, or HVAC system maintenance on industrial facilities, sheet metal workers round out the core trade set.

All four of these figures come from BLS OEWS May 2024 and represent national estimates. For the current release — which may now reflect May 2025 data — visit bls.gov/oes directly.

The Local Rate Is the Number That Actually Wins (or Loses) the Hire

The national medians above are your starting point, not your finish line. Industrial maintenance work is concentrated in specific geographic clusters — Gulf Coast petrochemical corridors, Rust Belt manufacturing belts, Appalachian energy regions — and wage rates in those markets can deviate substantially from the national figure in either direction.

A pipefitter working a turnaround in a major Gulf Coast refining hub is not competing against the national median. She is competing against every other industrial employer in that MSA. If your offer is anchored only to the national figure and the local market is running materially higher, you will lose that hire — and probably not know why.

Here is how to find the local number:

1. Go to bls.gov/oes and select "OES Data" → "State and Area" data.
2. Choose your state, then drill to your metropolitan statistical area (MSA — the labor-market geography BLS uses, typically anchored to a major city and its surrounding counties).
3. Look up the SOC code for the trade you are benchmarking (e.g., 47-2152 for pipefitters).
4. Pull the median and the 25th/75th percentile for your MSA.

One caution: BLS suppresses estimates for occupations with too few sampled workers in a given area — typically fewer than 10 estimated employees — so some smaller MSAs will show no figure for a specific trade. When that happens, fall back to the state-level estimate, and note that in your comp documentation. Our Houston skilled trades wages article walks through this exact process for one of the country's densest industrial maintenance markets.

Industrial Maintenance Wage Benchmarking in Practice: Building a Salary Band

A percentile from the BLS table is not an offer — it is raw material. The goal of industrial maintenance wage benchmarking is to convert that raw material into a defensible salary band: a minimum, midpoint, and maximum that reflects your market position and your internal equity.

Here is a worked example anchored on real BLS data:

Trade: Pipefitter (SOC 47-2152) Anchor: National median, May 2024: $62,970/yr

Step 1 — Choose your market position. If you want to be competitive in a tight industrial labor market, position your midpoint at or near the 75th percentile, not the median. The 75th percentile means three out of four workers in that occupation earn less than that figure — it is where you go when you need to win a competitive hire. If you are benchmarking against your MSA data (recommended), use the MSA 75th percentile as your midpoint target; if the MSA is suppressed, use the state 75th percentile.

For this worked example, we will use the national median of $62,970 as the midpoint to illustrate the method. In practice, substitute your local 75th percentile if the market is tight.

Step 2 — Apply a spread buffer. A typical salary band spans ±20% around the midpoint. This is a common methodology; your HR advisor or compensation consultant can help you size the spread to your internal structure.

• Midpoint: $62,970
• Minimum (−20%): $50,376 (round to $50,400)
• Maximum (+20%): $75,564 (round to $75,600)

Step 3 — Document the anchor. Your band is only as defensible as its source. Note the SOC code, the geography, the release date, and the percentile you anchored to. If a candidate challenges your offer, you can point to the methodology — not "that's what we paid last time."

This is a worked example to illustrate the method. The arithmetic is round-number modeling; substitute your actual local BLS figures and run the calculation for each trade in your workforce. Our multi-trade wage comparison article applies this approach across all four industrial maintenance SOC codes side by side.

Why the Same Tools That Work for Construction Work for Your Shop

The SOC taxonomy is the insight that unlocks industrial maintenance wage benchmarking. Because BLS organizes wage data by occupation — not by your employer's NAICS code — the same data infrastructure that a specialty trade construction firm uses to benchmark electricians works equally well for your maintenance shop benchmarking the same electrician SOC (47-2111, national median $62,350/yr, May 2024) when your industrial facility has licensed electrical maintenance techs on staff.

This matters for tool selection. Most wage-benchmarking platforms were built for either (a) large enterprise HR departments with dedicated compensation analysts or (b) white-collar tech and professional services roles. Neither category maps well to a 30-person industrial maintenance shop that needs to price an offer for a certified welder by end of day. Our skilled trades wage benchmarking guide walks through the full landscape of how trade employers are solving this problem today — from manual BLS CSV downloads to purpose-built platforms.

At SkilledMarkets, we built specifically for this gap. Our platform pulls BLS OEWS + O*NET data for every trade SOC code — welders, pipefitters, equipment operators, sheet metal workers, and the full construction and industrial maintenance spectrum — and surfaces them through a salary-band generator that converts national and local percentiles into an offer-ready min/midpoint/max band. Starting at $199/mo, it is built for the shop that cannot afford an enterprise compensation suite but also cannot afford to keep losing hires to a competitor who looked up the number before you did. See our full feature set and pricing.

Start Benchmarking Before the Next Resignation Letter

The pipefitter who left last Thursday already has a new offer letter. The one who stays is watching to see whether you respond — or whether you wait until the next resignation to figure out what the market is paying.

Industrial maintenance wage benchmarking does not require a compensation department. It requires the right data, organized by the SOC codes your trades actually carry, pulled to the geography where you are competing for labor. The BLS has the data. The question is how long it takes you to get to it.

Start with the national figures above. Pull your MSA data from bls.gov/oes. Build one band for your most at-risk trade this week. Then decide whether you want to do that manually every time a candidate counters — or whether a 14-day free trial of SkilledMarkets is worth an afternoon.
